Yes we are, since a couple of months. $ git grep -l SSEi_REVERSE_STEPS *fmt*c mssql-old_fmt_plug.c mssql05_fmt_plug.c mssql12_fmt_plug.c nt2_fmt_plug.c rawMD4_fmt_plug.c rawMD5_fmt_plug.c rawSHA1_fmt_plug.c rawSHA224_fmt_plug.c rawSHA256_fmt_plug.c rawSHA384_fmt_plug.c rawSHA512_fmt_plug.c I mostly just put the mechanism in there, more can be done - especially for SHA-2 which currently only skip the final constant addition. magnum
